Our retina and occipital cortex undo a lot of rendering (e.g. line detection), therefore, a theory: It will take such a long time to get realistic VR, that we will have direct neural interfaces that are much simpler because they can skip the encoding/decoding. \tanget And perhaps at higher semantic neurons, so we can just invoke the concept of "cool graphics" without actually having to simulate it...
